ui: state list: add data column.

[makasim]

The source data for the column are annotations in the format data:{id}:{rev} (source.

UI has to parse the state annotations take all that starts with data: and print them as buttons or links (one per line). Once clicked the API call GetData should be performed. The result is printed in a popup.

The link title in the format: {ID}:{Rev}

I've changed the data spec:

changed b type bytes -> strings added binary bool.

So, in popup

• display d.ID, d.Rev and d.B separatly (not as json).
• display b
  • if binary false (means d.B is safe text) and d.B valid json (pretty print and display as json)
  • if binary false and d.B NOT json just display d.B as is.
  • if binary true (means d.B is base64 encoded binary) display d.B as is
